Question

the base of a triangle measures 32 cm and altitude is 45 cm find the area of triangle in square metres ​

Answer 1

GIVEN :

the base of a triangle = 32 cm

altitude = 45cm

TO FIND :

the area of triangle in m²

FORMULA USED:

Area of triangle =

$\frac{1}{2} \times base \times altitude$

SOLUTION :

To find the area of triangle in m² we will use the formula :-

$➮\frac{1}{2} \times base \times altitude$

Where it is given that =>

• base of triangle = 32 cm
• altitude = 45cm

--------------------------------------------

to find answer in m² , we will convert 32cm and 45cm in metre.

we know :- 1cm = 1/100 m

therefore , 32 cm = 3/100m and 45cm = 45/100m

-------------------------------------------

$➮\frac{1}{2} \times \frac{32}{100} \times \frac{45}{100}$

➮\frac{16}{100} \times \frac{45}{100}

[tex]➮\frac{16×45}{100}

[tex]➮\frac{720}{100}

[tex]➮7.2 m²

ANSWER :

7.2 m²

1. Area of square = (side)² or a²
2. Area of circle = π × (radius )²
3. Area of rectangle = length × breadth

Also :-

1. 1 cm = 1/ 100 m
2. 1 m = 100 cm
3. 1km = 1000 m
4. 1km = 100000 cm
5. 1km = 1000000 mm
